Did you catch the Green Hill Zone reference in the piano? How about pixel Sonic on the right (inspired by http://snakestitch.wordpress.com)?

As an aside, I started out in the game music community as a MIDI sequencer in the late 90’s, submitting transcriptions of videogame pieces to the Video Game Music Archive. (You can still find a lot of my work there under the alias Sirius. Don’t laugh too hard! I was super young.) I have a lot of admiration and respect for sequencers, as it requires both precision with one’s ear and precision in execution, which in turn requires a command of the technology. Dave and I started talking because of our common history with vgmusic.com (and our common adoration for soundtracks like Bomberman 64) and it’s been an absolute pleasure to get to work with someone who I share some sensibilities with. Plus, I get to show my appreciation for an art form that’s quite sentimental to me, and I wouldn’t be here today without it!
